HARRY S. FOLG-EB AND JOSEPH C.- JULIEN, OF CHICAGO, ILLINOIS; SAID JULIEN ASSIGNOR TO SAID FOLGER.

SELF-INKING- HAND-STAMP.

To aZZ to 710m it may concern:

Be it known that we, HARRY S. FoneER and J osnrrr G. JULIEN, citizens of the United States of America, and residents of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Self-Liking HandStamps, of which the following is a specification.

Our invention relates to self-inking hand stamps, and has for its object improvements in such stamps.

In the accompanying drawings Figure 1 is a front elevation; Fig. 2 is a side elevation; Fig. 3 is an enlarged central section corresponding to Fig. 1; Fig. 4 is an en larged section on line l1 of Fig. 2; Fig. 5 is an enlarged rear elevation showing one end of the spring shaft and associated parts;

Fig. 6 is a sectional elevation similar to Fig.

5; and Fig. 7 is a side or face view of the ratchet wheel on the spring shaft.

The general type of self-inking hand stamp herein illustrated is comparatively new in its commercially practical form. In making up these stamps for commercial use it has been discovered that, for some sizes, it is desirable to provide better protection for the side plates of the stamp, and protection for the hands of the operator to prevent them from striking the side plates to the discomfort of the operator when using the stamp. "We accomplish these results by reconstructing the guides and slides of the stamp so as to inclose the side frames and at the same time have the upper end of the guide slot bridged over by the metal of the side frames without making the entire apparatus unusually high for the size of the stamp, used.

The stamp 10 provided with the handle 11 reciprocates in a frame composed of said plates 12 and 13 connected together below by a bridge or tie 1d. The side plates have vertical slots 15 which have their ends closed above and below by the metal of the side plates. That part of the metal which closes the upper ends of the side plates is shown at 16 in Fig. 3. The metal removed to form the slots is pushed or forced outward in the form of flanges 17 adapted to form guides. Heretofore, in small sizes of stamps, the upper ends of slots 15 have been left open to the material weakening of the frame, or have been bridged over by special pieces of Specification of Letters Patent.

metal, or else the side plates have projected so high that they are frequently struck by by the hand of the operator in using the stamp. The first of these constructions is shown in Patent No. 1,132,519, to Folger and Redfield, the second is shown in appli cation No. 1,071, filed by Folger and Ross; and the third is shown in application No. 851,041, filed by Folger and Redfield.

Secured by the screw 18 between the stamp 10 and the handle 11 is a bridge 19 having depending legs 20 bent to form slides which inclose and cooperate with the guides 17. Running through the stamp 10 and slots 15 is a tie rod 21 which is secured to the lower ends of the legs 20 and holds them from displacement with respect to the guides 17. By the construction herein shown there is only one pin or projection to extend through the slots 15 with the result that those slots may be closed at their upper ends and at the same time the side plates may be short enough to be inclosed by slides of moderate length.

An ink pad 22 is pivoted on a rod 23 supported on the side plates 12 and 13, and links 24 extending from the tie rod 31 to the pad frame serve to move the pad to and from the stamp when the stamp is reciprocated in the stamp frame composed of the side plates. Springs 25 on shaft 23 serve to elevate the stamp in the stamp frame.

One end of the shaft 23 has a screw-driver slot 26 (Fig. 6) cut to a depth which extends beyond the shaft bearing in plate 12, and a ratchet wheel 27 is mounted upon the shaft 23 just inside of the frame 12. The shape of this ratchet wheel is shown in Fig. 7, in which the bar or bridge 28 fits into the slot 26, while the parts of the shaft 23 on each side of the slot fit into the openings 29 on each side of the bridge 28. The ratchet wheel 27 is punched from sheet metal and when slipped on the shaft 23 as described is securely held without special fastening.

The pawl 30 cooperating with this ratchet wheel is pivoted to the plate 12 (Fig. 5) and has an ofiset end 31 which extends between the wheel 27 and part of the swinging frame 32 which holds the pad 22. As so constructed the pawl 30 is not liable to displacement with respect to the wheel 27 on account of looseness in adjacent parts. A screw driver applied to slot 26 to turn shaft 23 serves to vary the tension of springs 25, and pawls 30 serve to hold such tension.

What we claim is:

1. A frame consisting of side plates hav- If ing guides formed on their outer faces, a

bridge extending over the tops of the side plates and having legs in the form of slides engaging said guides, a stamp suspended from the center of the bridge, and a tie extending through the stamp and serving to connect the lower ends of said legs together.

2. A frame consisting of side plateshaving closed slots therein and guides on the outer faces adjacent to the slots, a bridge in the form of an inverted U the legs of which inclose the side plates and are guided by said guides, a stamp suspended from the bridge and between the side plates, and a tie extending through the slots in the side plates and serving to hold the lower ends of the bridge legs from displacement.

3. A frame consisting of side plates having slots therein and laterally extending guides on the outer faces of the plates adj acent to the slots, the upper and lower ends of said slots being closed by the metal of the plates in which said slots are formed, a bridge extending over the tops of the side plates and having depending legs in the form of slides engaging said guides, a tie rod connecting the lower ends of the slides together, and a vertically reciprocating stamp located between the side plates and connected to said tie rod.

i. In a hand stamp, a frame, a vertically reciprocating stamp, a pad frame, a shaft upon which the pad frame is pivoted, connections between the pad frame and the stamp, a stamp elevating spring mounted upon the shaft, means by which said shaft may be adjusted to vary the tension of said spring, and a pawl and ratchet connection for holding such tension, said pawl being provided with an extension resting between the ratchet and pad frame and serving to hold the connection between the pawl and ratchet.

5. In a hand stamp, a stamp elevating spring, means by which the spring tension may be adjusted, and a pawl and ratchet device for holding such tension, said pawl having a projection extending to one side of said ratchet. I

6. In the spring tension device of a hand stamp, a shaft provided with a screw-driver slot in the end thereof by which the shaft may be turned to adjust the spring tension, a ratchet wheel arranged to move axially on the shaft and provided with an integral portion extending into said slot and a pawl engaging said ratchet.
